IDAHO FALLS, Idaho, May 16, 2024 /PRNewswire/ -- International Isotopes Inc. (OTCQB: INIS) (the "Company" or "INIS") announces its financial results for the three-month period ended March 31, 2024.

Revenue for the three months ended March 31, 2024, was $2,904,458 compared to $3,089,535 for the same period in 2023.  This was an overall decrease of approximately 6%. The decrease in revenue for the three-month period was largely the result of continued global isotope shortages of Cobalt-57 isotopes impacting our Nuclear Medicine segment. 

The Company reported a net loss for the three months ended March 31, 2024, of $154,051 compared to net loss of $148,054 for the same period in 2023. This is an increase in net loss of $5,997 that is largely the result of the decrease in revenue in our Nuclear Medicine Standards Products segment partially offset by increased revenue in our Theranostics Products and Cobalt Products segments and increased gross profit percentages for the three months ended March 31, 2024, as compared to the same period in 2023.

As of March 31, 2024, cash and cash equivalents of $2,368,496 as compared to $2,688,141 at December 31, 2023. For the three months ended March 31, 2024, net cash provided by operating activities was $412,444 compared to $981,311 for the three months ended March 31, 2023.

The following provides a summary of our current business segment performance for the three-month period ended March 31, 2024:

Theranostics Products

Revenue from the Theranostics Products segment increased approximately 8% for the three-month period ended March 31, 2024, compared to the same period in 2023. The increase was primarily the result of continued growth in demand for our radiopharmaceutical product (generic sodium iodide I-131).  This sodium iodide radiopharmaceutical drug is used to treat thyroid cancer and diseases, and we are currently the only domestic manufacturer of this important theranostic radiopharmaceutical drug product. We expect continued growth for our Theranostics Products segment for 2024 due to continued demand for generic sodium iodide I-131 products.  We also expect the addition of the EasyFill Automated Iodine Capsule System along with its consumables & accessories in our Medical Devices segment to support our sales in this segment.

Nuclear Medicine Segment

Revenue from nuclear medicine products for the three months ended March 31, 2024, was $765,408, compared to $1,168,831 for the same period in 2023. This represents a decrease in revenue of $403,423, or approximately 35%. The decrease is due to a global shortage of Cobalt-57 isotopes during the three months ended March 31, 2024. We continue to maintain a growing backlog of orders and we expect a revenue catch-up upon normalization of the global isotope supply chain, anticipated by the end of the third quarter of this year. Overall, we anticipate growth of the Nuclear Medicine Products segment upon normalization of the supply chain and as we continue to add new products, customers, and territories.

Cobalt Products

Revenue from the sale of Cobalt Products for the three months ended March 31, 2024, was $233,968, compared to $158,308 for the same period in 2023. This represents an increase of $75,660, or approximately 48%. Large value sales of high activity cobalt sources occur at various times throughout the year. Frequently the timing of these sales can have a significant impact on period comparisons. The Company remains the only domestic manufacturer and supplier of high activity cobalt-60 sealed-source products and we anticipate overall yearly growth in this segment in 2024 due to existing orders planned for manufacturing later this year.

Medical Devices

Medical Devices is a new reportable business segment starting in the first quarter of 2024. While we have not yet commercialized any medical devices, we have invested in this segment throughout 2023 and 2024 and anticipate additional investments for the remainder of 2024 with commercialization of products starting later in 2024. This segment will include The Swirler® and Tru-Fit™ Mouthpiece with related accessories under the RadVent brand. Additionally, the Company has investments in a joint venture arrangement for our EasyFill Automated Iodine Capsule System.

Shahe Bagerdjian, President & CEO of the Company, commented, "First quarter results delivered a promising start to 2024, despite continued global isotope constraints impacting our RadQual products. Theranostics Products delivered a promising start to 2024, compounding on last strong growth, and we expect the trend to continue into the next quarter. We remain focused on resolving our raw material shortages impacting the Nuclear Medicine Products segment. We are working with various parties, including the U.S. Department of Energy, to help alleviate the shortage. While we successfully added a new cobalt-57 supplier in the first quarter, demand significantly outpaced our supply."

"We are encouraged by the growing demand of our non-Cobalt-57 products and reached various development milestones for new Nuclear Medicine and Medical Device products. We believe the Company will begin commercialization of these new products in the second half of 2024."
